all_pairs

Create all possible pairs

Create all possible pairs of two character vectors.

all_pairs(x, y = character(0), sort = FALSE, result = "matrix")

names2pairs(x, y = NULL, sort = TRUE, result = "list")

NOTICE: If y is not NULL then x and y must be disjoint (no checks are made); otherwise pairs of identical elements wil also be obtained.
